TELLEFIS WINDOW.

Specication of Letters Patent.

Patented April 2, 1907.

Application filed March 21, 1906. Serial No. 307,178.

To @ZZ whom, t may concern,.-

Be it known that I, EMERY LIBERTY, a citizen of the United States,residing in the borough of Manhattan, city of New York, county and Stateof New York, have invented certain new and useful Improvements inTellers Windows, of which the following is a specification.

This invention relates to improvements in tellers windows of the typeshown in my Patent No. 774,190, dated November 8, 1904, which ischaracterized by a window which may be elevated above the counter, sothat a larger opening will be produced when desired.

The objects of the present invention are to simplify the construction ofthe mechanism, render it more certain and silent in operation, and otherobjects, which will more fully appear from the following specificationand claims.

I attain these objects by the mechanism illustrated in the accompanyingdrawings, in which Figure 1 is a perspective view of a window, counter,and operating mechanism for the wicket. Fig. 2 is a top view of theoperating mechanism, and Fig. 3 ya slide elevation thereof. Fig. 4 is adetail of the portion of the mechanism shown in Fig. 3, showing theparts in the position they will assume with the wicket raised.

ln all the views like parts are designated by the same referencecharacters. v

In carrying out my invention I'provide the wicket or window 1, which isarranged above the counter 2, as disclosed in my patent before referredto. The wicket 1 has depending side portions 3, which pass through opennings in the counter and slide within the guides or ways 4 in the sidesof the window. Provision is made to permit the wicket to be raised tothe position shown by the dotted lines in Fig. 1. This raising mechanismis as follows: The two depending portions 8 are connected together bythe horizontal crosspiece 5. To this cross-piece is secured a verticallifting-rod 6. The upper end of the latter may be forked, as shown, andsecured to the cross-piece 5 by means of a pin, so that an exact nicetyof alinement between the rod 6 and depending portions 3 is not necessaryto be attained in order to get a smooth operation. The rod 6 extendsdown below the counter and passes through a guide or bracket, which isshown as an angular plate with a hole through it, through which the rod6 passes. This guide or bracket 7 is secured to a backing 8, which maybe a plate of sheet metal, a board, or other device, secured to aportion of the support of the counter. The elevating mechanism and lockare secured to and carried by the backing 8.

The elevating mechanism comprises a chain 9, which is secured to the rod6 by means of a clip 10. This chain 9 passes over a sprocket-wheel 11,which is mounted upon 'a shaft 12, which turns in bearings carried bythe backing 8, and a frame 13, formed of an upright piece and ahorizontal piece connected together, as shown. The other end of thechain 9 is connected to a counterweight 14. This counterweight is in theform of a box, having a bail to which the chain is attached and providedwith the clips 15, which engage with a guide-rail. The guiderail 16 isvertically arranged in a proper position so that the weight 14 willslide up and down upon it. The guide-rail is T-shaped in crosssection(see Fig. 2) and is secured by bolts or rivets to the backing 8, theshape of the rail permitting the clips 15 to engage with the edges ofthe rail and to guide the counterweight, preventing it from coming outof contact with the rail. The box constituting the counterweight may bemade with walls sufficiently thick to constitute a sufficient weight, orif additional weight is required it can be made by introducing shot orother weights into the box 14.

The sprocket 11 is rotated by means of a pinion 17, free to turn uponthe shaft 12 (see Fig. 2) and provided with a finger 18. This finger isadapted to engage with the nger 18, carried by the sprocket 11, when thepinion 17 is rotated, and thereby constitutes aV lost-motion connectionbetween the pinion and sprocket. The pinion 17 is rotated by means of arack 19, which is connected to and carried by a rod 20. The rod 20passes through a hole in the bracket 7, and its lower extremity isconnected to a pedal 21. As shown in Fig. 1, the pedal 21 is fulcrumedupon a support 22, which rests upon the iioor, and its inner end isconnected to the lower end of the rod 2O by means of a link 23, a secondlink 24, formed of a plate engaging between notches in the extremitiesof the link 23 and rod 20, connecting the two latter together. The rod20, rack 19, and lever 21 are so arranged that upon the teller depress-IOO ing the outer end of the pedal with his foot the rod and rack 19will be elevated, rotating the pinion 17 and causing the finger 1S toengage with the finger 18a, which in turn will rotate the sprocket 11,lift the rod 6, and with it the wicket 1. The sprocket 11 is preferablymade sulliciently large so that the wicket may be completely elevatedthrough not more than one revolution of the sprocket.

The rack 19 is held in engagement with the pinion 17 by means of aroller 25, which is carried upon a support 26, which is secured to thebacking or base plate 8 by means of screws, which pass through slots inthe support and permit of adjustment of movement of the roller 25 inrelation to the rack 19.

In order to prevent the wicket from being elevated except by the pedal,a lock is provided. This lock, as shown, consists of a friction-clutch,which engages with the rod 6. The clutch is shown as formed of a plate27, which has a central opening through which passes the rod 6. Thisplate is secured by a screw 28 to the bracket 7. The opening throughwhich the rod 6 passes is sufficiently large to make a loose lit, andthe connec tion with the plate 27 and screw 28 is sulliciently loose topermit some movement of the plate upon the bracket. This plate willserve the purpose of a clutch to prevent the elevation of the rod 6except by the pedal. It is pressed upward into engagement with the rodby means of a spiral spring 29, which surrounds the rod and also engageswith the plate 27. The other extremity engages with a second bracket 30,through which the rod 6 also asses. As shown in the drawings, the braciets 7 and 30 are formed of one piece of sheet metal bent to the shapeillustrated to form a support for the clutch-plate 27 and the end of thespring 29.

The plate 27 is depressed by means of a dog-31, which is carried inbearings on a standard 32, which in turn is supported by the bracket 7.One end of the dog engages with the clutch 27. The other end comes incontact with a cameplate 33, carried by the rod 20, by means of which itmay be tilted. This cam-plate 33 extends up above the bracket 7 only ashort distance and ends at a point below the dog 31 when the plate 33and rod 20 are in the lowermost position. This lowermost position isdetermined by a stop 341, which may be in the form of a pin passingthrough the rod and engaging with the bracket 7. It will be seen thatwhen the parts are in position shown in Fig. 3 the dog 31 will merelyrest on the top of the camplate 33, allowing the spring at 29 to elevatethe clutch-plate 27 and canse the latter to lock the rod 6 againstvertical movement. When the rod 20 is elevated, the dog 31 will beengaged by the top of the cam-plate '33 and tilted, depressing theclutch-plate 27 and permitting the rod 6 to be elevated.

The operation of the device is as follows: Ordinarily checks,pass-books, &c., are passed over the counter 2 and under the wicket 1.Should it be necessary for any purpose to increase the size of thewindowopening, the teller depresses the pedal 21. This elevates the rod20 and rack 19, rotating the pinion 17. It also elevates the cam 33,depresses the clutch 27 through the agency of the dog 31, and willpermit the elevation of the rod 6 and with it the wicket 1. The pinion17 is free to rotate a certain distance before the lingers 1S and 13Lcome into engagement. This distance is sufficient to permit theelevation of the cam 33 a sufficient distance to cause a disengagementof the clutch 27 with the rod 6. As soon as this has occurred thefingers 13 and 1Sa will come into contact with each other and thesprocket 11 will be rotated by the rotary movement of the pinion 17.This will elevate the chain 9 and rod 6 and with it the wicket 1. Thewicket will remain open so long as pressure is applied to the pedal 21.Upon the teller removing pressure from the pedal the weight of the rack19, rod 20, and cam 33 will be sufcient to quickly overbalance the otherside of the pedal. The parts will immediately descend to the pesitionshown in F ig. 3. This will not rotate the sprocket 1 1, for the reasonthat the pinion 17 will be free to rotate in the other direction fornearly a complete revolution before the fingers 1S and 18a will againcome in contact. Pressure having been removed from the pedal 21 and therod 20, cam 33, and rack 19 having been allowed to descend, the wicketwill descend also, but not so rapidly, as it is counterbalanced to someextent by the counterweight 14. The clutch 27, however, will be put intoaction the moment the cam 33 has entirely descended. Consequently thewicket will be locked against further open movement. Should an attemptbe made to open the wicket after the pressure has been removed from thepedal 21, such attempt will be unsuccessful, because the wicket will beguarded against open movement by means of the clutch 27. The clutch 27will act noiselessly and yet will be effective at any point of thevertical movement of the rod 6.

In order to prevent a too sudden jar upon the closing of the Wicket, thelower end of the rod 9 may be provided with a rubber button 35, which isadapted to engage with a bracket 36, carried by the support S.

By mounting the lifting and locking mechanism upon the support 3 theparts may be adjusted before being put in place. It is not absolutelyessential that the rod 6 engage with the center of the cross-bar 5,although the nearer it is to the center the less liability there will beof jamming in elevating the wicket.

By the construction described a single ele- Szo IOO

IIO

i vating device is employed. This has the advantage over my previouspatent, which employs a duplex arrangement engaging with each side ofthe wicket. I find in practice that this is not necessary, and a singlechain, clutch, &c., may be employed with equal success.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a tellers window, the combination with the wicket, of means for`raising the wicket, such means including a rod, and a lock for thewicket, such lock including a friction-clutch engaging with the rod.

2. In a tellers window, the combination with a wicket, of lifting andlocking means for the wicket, the said lifting and locking means beingcarried in oto upon a backingplate, in such a manner as to Jform anentirety adjustable independently of the wicket, and connections betweenthe lifting and locking means and the wicket.

3. In a tellers window, the combination with the Wicket, of a rod forlifting the wicket, a chain and sprocket for lifting the rod, apinionand a rack for rotating the pinion, and means for moving the rack,a cam moved by the rack, lost-motion connections between the pinion andsprocket, a friction-clutch adapted to engage with the rod, and a dogadapted to engage with the cam and release the clutch.
